Ulf,
We don't copy messages across queues. If you send a single message to a
multicast address it's only stored in memory once, and a reference to the
message is stored on the queue. You don't have noQueues * messages in
memory, but you do have some additional message references in memory.

Hi Andreas,
If I understand correctly you're wanting to create a single cluster, with
active-active style availability, with some satellite brokers?
To set up an active/active style HA cluster in Artemis, you can use using

in back pressure on the bridge, meaning that messages will build up in

Hi Lionel,
If I understand your use case correctly, then MQTT has a feature that does
exactly what you're trying to achieve. Retained messages.

If it's shared subscription like semantics you are after, you can also do
something similar with FQQN (which is available over all protocols and JMS

This is using a very old version of Artemis. I would recommend you bump
